Through the above operations, several detections may be completed. One is the position of the camera opening. If the pressure sensor 50 cannot produce The sensor signal proves that the position of the camera opening is deviated. The position detection block 46 is not inserted into the camera opening. If the pressure sensor 50 generates a pressure signal and the second contact sensor 47 does not generate a sensor signal, the camera opening is too large. If the second contact sensor 47 generates an induction signal, the pressure value of the pressure sensor 50 may be used to determine whether the thickness of the case 5 is acceptable, that is, if the pressure value exceeds the maximum induction value of the pressure sensor 50, the collection is proved The thickness of the case is not enough. If the pressure value is less than the minimum value of the set pressure sensor 50, it proves that the thickness of the case 5 is too large.
